Answer:
b) a large transient population that is constantly moving
Explanation:
Mexico City, one of the largest cities in the world, faces challenges in determining its actual population due to several factors:
1. Transient Population:
- Migration: Many people move in and out of Mexico City for work, education, and other opportunities. This high mobility makes it difficult to maintain accurate and up-to-date population records.
- Temporary Residents: A significant number of individuals might live in the city temporarily, contributing to the difficulty in getting a precise count.
While other factors like self-constructed housing in barrios, distrust of government officials, and the rapid influx of refugees may also affect population counting, the primary reason is the transient nature of the population, which causes frequent changes in residency and complicates the census process. This constant movement and fluctuation make it challenging to get an accurate and stable count of the population at any given time.
The actual population of Mexico City is unknown because of a) hundreds of self-constructed housing areas called barrios.
These sprawling slums are challenging to document and continually change, complicating accurate census counts. The actual population of Mexico City is unknown because of large transient populations, untrained census workers, popular distrust of government officials, and the rapidly growing influx of refugees.
However, the most significant reason is the presence of hundreds of areas with self-constructed housing called barrios that surround the city on the slopes of the central valley. These sprawling slums make it incredibly challenging to conduct an accurate census, as they are often poorly documented and continuously changing.
